Blended from circuit-archetype lineage, dynamic feel, tone-signal overlap and tone-vector distance — the tone vector itself is derived from editorial description text, not a measured acoustic signal, so this reflects how similarly the catalog copy describes the two, not a lab measurement. Shown only within a gear class, and only where there's enough evidence to be meaningful.36% — somewhat different

The Friedman Dirty Shirley is a 40-watt boutique tube head built around a modified Marshall JTM45 concept, voiced for vintage British classic rock crunch. It is big, beefy, chimey and articulate at once, with a remarkably touch-sensitive response that cleans up when you roll back the guitar volume and pushes into smooth, sustaining crunch when you dig in or turn up. Tweaked coupling and cathode caps give it a fat yet tight feel. It covers vintage Marshall plexi and hot-rodded gain tones and lower-gain territory, but is not built for pristine blackface cleans. Joe Perry runs multiple Dirty Shirley heads in his Aerosmith touring rig. Ideal for classic rock, hard rock and blues-rock.
The Mesa Boogie Fillmore 25 Head is a 25-watt two-channel amplifier with a distinctly late 1960s to early 1970s voicing, delivering fat clean tones through to the classic overdriven sounds reminiscent of Carlos Santana's signature breakup. Its two channels are identical in layout, each offering three voicing modes called Clean, Drive and Hi, so both channels can be set anywhere across the amp's range rather than one being fixed as the clean side. Power is switchable for smaller rooms. Unlike the Mark and Rectifier families it is deliberately a vintage-flavoured amplifier rather than a modern high-gain one. It suits blues, classic rock and roots players who want period voicing with modern build quality.
